グレー コードレスアドバンスト2.0 ウォーターフロッサー – グレー (WP-587)

Took it on a two-week trip and never once worried about the battery—the 4-hour recharge lasted the whole time without needing a top-up. The quiet motor also means I can floss in the hotel bathroom without waking my partner.

This thing is so quiet I actually double-checked it was running the first time I used it in the bathroom at 6am. The 4-hour recharge gets me well over two weeks of daily flossing, and the global voltage means I didn't have to worry about it on my trip abroad.

I travel a lot for work, so the global voltage and the fact it fully charges in just 4 hours are absolute lifesavers. It’s also noticeably quieter than my old plug-in model, which makes early-morning routines way less disruptive.
